WASTE VALVE FITTING Filed Jan. 14, 1927 Patented May 13, 1930 TOBIAS J. KAUFMAN, 0] CHICAGO, ILLINOIS WASTE-VALVE FITTING Application filed January 14, 1927. Serial No. 161,116.

My invention relates to plumbin devices and more particularly to fittings an valve or waste plug operating mechanism for lavatories.

.One of the objects of the invention is the provision of a new and improved waste plug operating mechanism in which a toggle having a spring as one of its members is employed.

Another object of the invention is the provision of a new and improved fitting for con-- necting the drain opening of alavatory directly to the drain pipe.

A further object of the invention is the provision of new and improved fitting and waste plug operating mechanism that is cheap to manufacture, easily assembled, eflEicient in operation, composed of few moving parts and that is not likely to become broken or et out of order.

ther and further objects and advanta es of the invention will appear from the ollowing description taken in connection with the accompanying drawings in which:

Fig. 1 is a vertical section of a lavatory showmg the invention in position thereon with parts broken away;

Fig. 2 is a section on line 2-2 of Fig. 1;

Fig. 3 is a diagrammatic view showing the valve or waste plug in closed position; and

Fig. 4 is a similar view showing the valve or waste plug in open position.

Referring now to the drawin s on which the similar reference characters esignate the same parts throughout the description, the reference character 5 designates a basin, lavatory or other receptacle 0 any approved construction having an overflow opening 6, a passage 7, and a discharge or drain opening 8 through its bottom wall, asare usual in such devices.

It is common practice to provide a sectional fitting between the basin and the upper end of the drain pipe or tail piece. This has heretofore been deemed necessary because of the fact that the upper portion containin the valve is provided with an integral ange which necessitates the insertion of the fitting in the lavatory opening from the top. The making of this fitting in separate pieces and assembling the same from these pieces is obectionable because of the'added cost of time and labor in the manufacture of the separate parts. This objection is overcome by roviding a single simple. tubular fitting 9 for this purpose. a

The fitting 9 extendsdownwardly through the opening 8 and is flanged at its upper end as at 10 for compressing the packing 11 in the flared upper portion of the openmg 8 for formin a water tight joint. The lower end of the fitting is detachably connected to the upper end of the drain pipe or tail piece 12 in any suitable manner. As shown the tubular fitting 9 is internally threaded for engaging the threaded upper end of the pipe 12. The fitting 9 is provided with a plurality of openings 13 in its side wall in alinement with the passage 7 through which water may escape from said assage into said drain pipe or tail piece. crew threads 14 are provided on the intermediate portion of the tting 9 for receiving the clamping nut 15, for clamping the gasket 16 against the under side of the lavatory, for forming a wa-' ter tight joint, between the fitting and the lavatory. A rigid annular member 17 may be inserted between the nut 15 and the gasket for more efliciently clamping said gasket.

The lower end of the fitting below the threaded portion is slightly reduced whereby the nut 15 may be readily slipped over the same in assembling the device.

A waste plug or valve 18 ofany suitable form is slidably mounted in the drain tubular fitting 9 and its head 19 is adapted to engage a seat 20 on said fitting, when the plug is in lowered position in the usual manner.

The means for operating the waste plug or valve 18 will now be described. It consists of a spring pressed toggle for holding the valve in either open or closed position. The fitting 9 is provided with an opening 21 through which the valve operating mechanism is adapted to extend. Suitable means are provided for supporting the valve operating mechanism. In the form of the device selected. to illustrate one embodiment of the invention, a plug 22 having an axial bore 23 is employed for this purpose. The plug is secured in the opening 21 in any suitable manner as by bein threaded therein. In order to firmly attac the plug 22 to the fitting 9 so that the operating mechanism will not cause the plug to become loosened or detached, the wall of the fitting 9 is enlarged as by providing a radiallyextended portion or boss 210 through which the opening 21 extends. By means of this arrangement the threads are continuous aboutthe opening for rigidly securing the plug in position. The outer end of the bore in the plug 22 is cylindrical for receiving the spherical end 24 of the toggle link 25. The plug 22 is provided with a conical shoulder 26 for limiting the inward movement of the member 24. A gasket 30 is preferably inserted between the shoulder 26 and.

the spherical member 24 for forming a Water tight joint. The link'25 is provided with an extension 27 for engaging an; opening 28 in the stem of the valve or waste plug 18 for raising and lowering the same. The inner end of the opening through the plug 22 is flared as shown at 29 to permit vertical movement of the extension 27. The other tog le link 31 is in the form of a leaf spring, preierably approximately. U shaped, having its inner end bifurcated and connected to a pin 32 extending across the bifurcated end 33 of the link 25, see Fig. 2. The outer end of the spring 31 is connected to a pin 34 extending across the outer. end of the U shaped support 35 which is rigidly connected to the plug 22 and extends outwardly therefrom.

Suitable means are provided for operating the toggle formed by the link 25 and the spring 31. When the device is used on a lavatory, as shown, a handle or knob 36 is provided for this purpose. The handle 36 is placed ina convenient position above the lavatory 5. It is connected to the toggle through the medium of the stem 37 and the link 38. The stem 37 passes through the sleeve or bushing 39, preferably threaded at each end for receiving flanged nut or head 41, and the clamp nut 42, for attaching said sleeve to said lavatory. The stem 37 is connected at its lower end by a ball and: socket joint 43,

with the link 38. The link 38 comprises the screw threaded rod 44 and arm 45. The arm 45 is pivotally connected to-the pin 32 at its lower end, between the bifurcated ends of spring 31. It is adjustably connected to the rod 44 at its upper end as by being screw threaded thereon. A lock nut 46 holds the part in adjusted position.

In assembling the device, the arm 45 is so adjusted on the rod 38 that the lead spring 31 will be under initial tension, whereby the said spring will not only hold the spherical member 24 within the sleeve or cylindrical portion of the plug 22, but will also hold the valve stopper or plug 14 tightly on its seat, when the parts are int-he osition shown in Fi 1.

The spring 31 will a so be under tension w en the plug 14 is elevated 61m the same will be held in inoperative position by the resiliency of the spring.

In the operation of the device, when it is desired to move the valve from the closed position shown in Figs. 1 and 3 to the open position as shown in Fig. 4, the handle 36 is pressed down, which W111 move the pin 32 below dead center and the expansive force of the spring 31 will snap the valve to elevated position and hold it there as shown in Fig. 4. On elevating the knob or handle 36, the to gle will move u wardl past dead center an the spring wi sna t e valve to closed position and will hold t e same tightly on its seat, as shown in Figs. 1 and 3, to

form a water-tight joint.

It is thought from the foregoing taken in connection with the accompanying drawings ing and closing said valve, said means comprising a pivoted actuating member forming one link of a toggle, a spring formin the other link of said toggle and a push ro engagin an intermediate portion of said toggle or operating the same.
